LOCKING PIN OR BOLT.

SPECIFICATION forming part of Letters Patent No. 595,155, dated December'7, 1897.

Application filed February 8, 1897. Serial No. 622,465. (No model.)

To all whom it may concern.-

Beitknown that I, FRANK ERXLEBEN,a citizen of the United States,residing at Vayne, in the county of Vayne and State of Nebraska, haveinvented certain new and useful Improvements in Locking Pins orBolt-sand I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to certain new and useful improvements inlocking-pins, the object being to provide a special construction of pinadapted to hold the two portions of a windmill-pump plunger together,whereby the said two portions of the plunger may be quickly andconveniently connected together or disconnected for pumping by wind orhand power.

To this end my invention consists in certain novel constructions,combinations, and arrangements of parts, as will be hereinafter morefullydescri bed, and specifically set forth in the appended claim.

In the accompanying drawings, Figure 1 is a side view showing theadjoining ends of the two portions of agiwindmill pump plunger and myimproved device connected therewith. Fig. 2 is a horizontal section ofthe same on the line 2 2 of Fig. 1. Fig. 3 is a detail perspective viewof the locking-pin and connections removed.

Like numerals designate like parts throughout the several views.

In windmill-pumps of ordinary construction the two portions of thepump-plunger are connected by a small pin passing through openingstherein and having its end confined by a split key. The objections tothis manner of connection are many and obvious, the chief of which beingthat when the pump stops for lack of wind and hand-power becomesnecessary this pin has to be taken out in order to disconnect the twoplunger members, which is a disagreeable piece of work, especially inthe dark or in cold weather. Another objection is that the said pin andkey, when disconnected, are very often lost, as they are not permanentlyconnected with the windmill-frame.

My invention contemplates the provision of a locking-pin devicepermanently connected with the frame and adapted to be instantly throwninto and out of connection, in order that the two members of thepump-plunger maybe readily engaged and disengaged without annoyance andinconvenience.

Referring to the drawings, the numeral 2 designates the two side piecesof one member of the pump plunger rod, which is connected with andoperated by the mechanism of the windmill, and 1 the plunger-rod, whichconnects directly with the plunger itself. My invention comprises alocking-frame 3, having three fixed sides, two of which, 4:, areparallel and have their ends 5 screw-threaded, said frame being adaptedto fit about the two side pieces of the plunger-rod member 2 andadjacent the lower end thereof. A clampingplate 6 fits upon the saidparallel sides l of the lockingframe and is confined thereon by nuts 7,engaging the said screw-threaded ends 5. The said clamping-plate andfixed side of the ,frame opposite said plate bear against two oppositepieces 2 of the windmill-plungerrod members, and thus clamp the framethereto. The said locking-frame is provided with a lateral extension 8,having an end flange 9, and a side standard 10, provided with a verticalslot 11. A pin or bolt 12 extends through openings in the said flange 9and the side of the frame from which the extension projects and isadapted to pass through opening 13 14 in the plunger-rod members 1 2 andconnect said members together. A lever 15 has one end connected by apivot 16 to the said locking-pin, and the rear end thereof is connectedwith a pin or bolt 17, passing through and occupying the vertical slot11 in the said standard 10 of the locking-frame. The other end of thelever is angularly bent and projects laterally beyond the lockingframeand constitues a handle portion 18. By moving this lever one way or theother it will be seen that the locking pin or bolt will be instantlythrown into and out of locking engagement with the said two members 1and 2 of the windmill-plunger rod. The locking bolt or pin when engagedto hold the two members of the plunger-rod is firmly held in suchengagement and cannot work loose.

My invention provides a simple and cheap construction of device which,unlike the pin commonly employed, is permanently connected to thewindmill-pump-plunger rod and may be thrown into and out of engagement,which is an obvious advantage over the ordinary locking-pin abovereferred to.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

In windmill-pumps, the combination with the two plunger-rod membersthereof, of a three-sided locking-bolt frame having two of said sidesarranged parallel with each other and provided with threaded ends, aclampingplate adapted to engage said threaded ends, an extension 8projecting laterally from said frame and having an end flange and a sidestandard provided with a vertical slot, a locking-bolt moving inopenings in the said frame FRANK ERXLEBEN.
